A couple of things to try here.

Basic Editing and Editor Options

Plone (the software this site runs on) allows you to edit pages with web-based WYSIWYG html editors (of your choosing via your account preferences), and also supports wiki-style page stub creation by enclosing any phrase with double-nested parentheses like this .  Clicking on a link that has a + superscript creates a new page referenced to the placeholder link.  Edit this page to see what the source looks like.

The default editor, Kupu, has a full-screen option by clicking on the expand icon in the upper right.  One thing I have noticed with Kupu, however, is that (sometimes) you may need to use the save (disk icon, upper left) before (also) using the plone-based Save button at the bottom of the content area, otherwise you will get a "content not saved" warning before moving on. [update: this seems to be related to this bug ; more in this recent thread.]

Edit or Comment

Page authors can use the 'Edit' tab to enable others to edit the content directly, or to allow threaded comments to content (blog-style).  This is useful if it is important to control the structure and content of the page, and make it more distinct from other's feedback.  On this site, it's generally a good idea to turn on comments for lightweight, quick feedback.

Images

Authors and editors can upload images.  The site software offers automatic generation of smaller versions of images from the originals to improve page layout, but full-sized originals can be used in-line or offered via links on a smaller version, such as this:

LaTeX and MathML Markup

Because some of the original content containted LaTeX-style markup for mathematical typesetting, this site has been modified to support in-line LaTeX-to-MathML markup, essentially using the approach described here.  This is purely experimental at this point, and browser support isn't all that pervasive yet.  Mozilla/Firefox is one option. Here's a tiny example:

$\frac{5*\sigma}{w}$

Workflow and State: Making Things Visible

Adjacent to the "Add new..." menu is a "State:" menu that allows you to control whether draft content is visible to the general site or not.  Be sure to remember to set the state to published if you want people to see when you have finished creating a new page.  You can read more about the workflow model that is fundamental to how Plone (and Zope, the underlying engine) works in the Plone "Basic Use" Documentation site.  To create an external (or internal) link like that one, just highlight the text you want as a link, and click the "insert link" icon in the editor toolbar (or you can do it in straight html if you prefer).

Adding Pages, Uploading Files, Creating Hierarchy

You can add a page, upload a file or image, or create a folder for other content by using the "Add new.." dropdown menu.

When folders are created, they don't have an editable "home" page by default, but navigating to a folder does list its contents.  You can also choose a page within a folder to be the "home page" of the folder, and it will be presented instead of the folder contents.

You can also hide uploaded files like images from the navigation tree (left column) if they don't make sense to view without a page that provides context.

All registered members can upload and author content in their own spaces, so you can always upload a presentation into your own area, and then link to it on any page.

Generating a Table of Contents, Presentation Mode

You can also use the "Setting" controls presented from the "Edit" tab to enable automatic generation of a hierarchical table of contents from Heading- and Subheading- formatted text.  Like this page has now.  Plone also offers a "Presentation Mode" that turns a page into a full-screen presentation.
